For what its worth, my mentality is more aligned with yours.

Consider there may be mental health issues at hand.

They smaller houses have two chimneys, connect the exhaust there. 

Their point is that some populations such as retirees, the disabled, sufferers of mental illness, etc. are willing to spend a greater proportion of their income on housing (their documents online explain this reasoning).

That said, we don't need to imagine that any of the requirements are infact insurmountable or exhaustive.  

It's been some time since I've been actively posting, so I thought I'd drop-in and update y'all on my experiences over the last two years.First, man I'm exhausted.

Negotiation is a mental/verbal sport, that's the best part for me.

I found a mentor in Dallas that I trusted and it enabled me to get the confidence up to purchase single family homes strictly for rental income in Dallas while I lived in Albany, NY.Now I have 10 deeds, 18 units as well as partial owner ship in 80 apartment units (doors) and live off the cashflow.I would suggest networking as much as you can in environments were investors have the abundance mentality and freely share information.  

Rents and expenses are not directly correlated, and any attempt to artificially correlate them through percentages is mental laziness that will result in inaccurate estimates.

And mentally prepare yourself to get a plane ticket at some point.
